Alice wants to track how regular she is at exercising. On a single line via Standard input, you're given her exercise record over several days. A Yindicates that she exercised on that day, and an N indicates that she did not. For example, an input line could look like: YYNYYYNNY A streak is defined as a set of consecutive days when Alice exercised i.e. a set of consecutive rs. Your task is to find the length of the longest streak in the input, and print that number on a single line to Standard Output, Example input YYNYYYNNY Output 3
